The only OIF bikes that relocated the filler were BSA singles.All the Triumph models such as the TSX and Harris bikes retained the original filler site.
I will mention the magical tube is more likely to aid in ventilation of the upper most part of the OIF cavity, so condensate will not build up in it. note the venturi set up were all the tubes converge.
Are the air intake tubes part numbers 83-5448 & 83-5449 missing from inside the airbox of this particular bike? Not sure how critical they are but they seem pretty hard to get hold of with most suppliers on back order.
Parts Book 1973 doesn't show the tubes. Parts book 1976, '77 does show them. I don't have Parts books '74, 75. But my '74 Norton came with the same style downward facing intake tubes in the air cleaner and I was told they were "sound suppressing" devices that pointed the "intake noise" down to the ground in order to comply with U.S. sound reducing laws. I expect the tubes in the Triumphs were for the same reason. We always removed the tubes (Triumph and Nortons) as we thought they restricted the intake air flow. They probably didn't, at least not enough to make a noticeable difference, but we were really cool back then and believed everything each other said. Thanks for watching and for writing. F.
I have a 71 Bonneville… just bought it and spent no time with it as o Drive a Truck OTR. Does mine have that “T” and forward breather pipe? or is this an aftermarket part?. Thanks.🇬🇧
1970 Triumphs were "small frame" bikes with separate oil tanks on the right side. 1971 and later Triumphs were (are) large frame bikes with the frame being the oil tank. If your bike has the oil in the frame (OIF) it should have the T-Fitting and the vent lines shown in the video. If it is an OIF bike and does not have the T-Fitting someone has removed it in the past. If it is a small frame bike with a separate oil tank it is a 1970 bike titled as a 1971. F.

Thanks. I knew I had seen the filler cap up at the top of the frame neck I just couldn't remember where/what/when. F.

T-Fitting and vent tubes are stock original parts.

@@fjdelmonte Well I guess it has been removed. Where would I find those parts please. Thanks for your reply.
